Abstract: A portable computer-based blood pressure monitoring system automatically measures heart rate and blood pressure using the auscultatory method. Measurements are performed at random time intervals to prevent the subject from affecting his blood pressure and heart rate due to the expected onset of measurement. Data representative of Korotkoff sounds and corresponding applied cuff pressures is stored in both digital form in a semiconductor random access memory (132) and in analog form on a serial magnetic tape recorder (112). The system automatically maintains occluding cuff pressure constant for a predetermined period after cuff inflation before performing measurements to prevent pneumatic ringing from affecting blood pressure measurements. After cuff deflation, values are derived which are representatives of the average of the highest Korotkoff sound level peaks and the average of all Korotkoff sound level peaks and serve to define a threshold value in relation to which the points of systolic and diastolic pressure measurements are determined.

Abstract: The present invention teaches a method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500 DEG F (149 to 260 DEG C) or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated. The radiant heat is derived from a flat faced electric quartz infrared heater which has a surface temperature in excess of 1600 DEG F (871 DEG C) and which is maintained for fifteen to forty-five seconds at a spacing of approximately one-fourth to one-half of an inch (6.35 to 12.7 mm) from the end face of the duct. The time varies with the size of the pipe being welded; and the heater to pipe spacing may vary widely, from 0.125 inch (3.175 mm) to as much as 2.0 inches (50.8 mm).
